To all 107150772 it may co'zwern:

Be it known that 1, B ain A. PETERSON, a citizen ot the United States, residing at Rockford, in the county of Ti inneba go and State of Illinois, have invented certain new and useful l niproven-leirts in Knot-Tying Implements, of which the following is a specification.

lhe invention relates to knot-tying devices such as are used in textile mills, and more particularly to that type 'which is adapted to he supported upon the hand of the mill operative and operated by a manipulation of the thuinh to unite the ends of thread or yarn.

The general object of the invention is to provide a lniotter of improved construction in which the parts are advantageously arranged, providing adevice which is efficient in operation, may he cheaply manufactured, and is capable of withstanding long, and hard usage.

A "further object of ther invention is to provide a knotter of improved construction in which the actuating mechanism is com pactly arranged and Wholly enclosed within a casing so as to be protected against dust and lint.

in the drawings wherein I have llldS- trated a preferred embodiment of the invention, Figure 1 is a side elevation of the improved lilt()tt1. Fig. is a central '\'-l'l'l(lzll sectional view through the knotter taken suhstantially on the line 2-2 of 1. Fig. 2} is a similar view taken in the plane of line of Fig. 2. Fig. t is a Vertical sectional view taken in the plane of line %d of Fig. 2. i

The knotter comprises generally an annular casing 2. having rotatably mounted diametrically thereof a stern or spindle 9 carrying" at one end a tying hill 3 and having; rigid therewith a pinion t On opposite sides of the casing are mounted a thread auide naemher 5 and a clamping device 6.

la the preent embodiment of the invention the guide ineinl'iers 5 and 6 are stationwith reference to the casingand the tyj hill 3 is adapted to he swung to effect the rotation thereof and. in such rotation, the tvingr of threads held in operative rela tion therewith and the amide member and clamping device For thus swingalily 4 supportin the tying: bill 3 and the spindle h which the hill is (writ-2d the spindle is section 1 and tits neatly within the end ot-110 knot-EWING IMPLEMENT.

mounted in an oscillatory ftrz'inie lira'c et i mounted 'coaxi-ally 'v.-'ithin the casing and operable in one direction "by means of a thumb lever '8. A spring 9 serves to restore the parts to their norinal position. To effect the rotation of the tying bill in such swing ing moven'i-ents, the pinion {t meshes withan arcuate rack or near segment 10 rigid with respect to the casing 1.

lhexcasing 1 is cylindrical insha-p'e and preferably is made from two in'terfitting sections 1 and 1. which sections may he secured together in any suitable way. The section 1 has rigidly secured upon its side wall a depending; hand portion 11 slot-ted to receive a strap (not shown) by means of which the device may be mounted. upon the hand of the operator. In the upper portion of the section 1 a slot 12 through which the tying hill extends, said slot serving to limit the swinging movements or" the tying bill.

The stem or spindle are v and the pinion 4; preterehly formed integral with each other, and the tying: hill 3 is suitably mount ed' at the upper end of the spindle. The bracket 7 is mounted. upon a cei'itral tubular stem 13 rotatahly mounted in the casing. Said intacIket comprises a plate or disk portion '7 having an include flange portion and an oppo, "tely disposed hearing lug 7". Said lug: provices a hearing-5 for one end of the spindle and to support the opposite end a lfiearine member 153 is secured Within the areuate flange portion T of the bracket whicn is located immediately Within the JQliDliGi'til wall of section 1" oi. the casino. Said flange portion is nade ot a length adapted in all positions ot the tying: hill relative to the casing to close the slot 12. The member 15 has socket 16 therein formed ecce'ntrically i reierenre to the spindle and torminq' a cam barrel adapted in the rotation ot the spindle to ettect the operation ot the tying: hill iii-the manner Well known in the. art To receive the spind e the tuhular stem. is erforated transr thereof, and to hold the spindle in operative position in the casing: it is provided with an annular groove 17 centraly thereot into which. projects the reduced inner end 19" oi a stud 18 carried by the casing section 1". Said stud is rigidly mounted upon the side Wall of the casing the tubular stem 13 to form a pivot theretor. lVhen the spindle is thus maintained .in operative position, the pinion a is held in mesh with the arcuate rack member 10, which latter is rigidly secured to the section 1 of the casing immediately adjacent the bearing member 7 of the bracket 7.

The thread guide member 5 is formed on the upper end of a plate 19 approximately circular :in form and rigidly secured to the side wall of the casing section 1 the guide 5 being formed on the periphery of said plate and projecting upwardly and slightly outwardly from the. upper edge thereof as shown in Fig. 2. The member is in the form of a hook and for the purpose of guiding the thread into the hook has a rounded guiding edge 5 (Figs. 1 and 2).

The thread clamping device 6, which is carried by the casing 1 upon the side wall opposite the guide member 5, comprises a pair of stationary plates 20 and 21 prov't ing stationary jaws 22 and 23 adapted to cooperate with a movable jaw 2% formed on an intermediate member 25. The members 20 and 21 are respectively secured to the peripheral and side walls of the casing section 1, and the intermediate member depends through a suitable opening in the periphe 'al wall of said section into the eas ing (Fig. 1). Atits lower end said member .35 may be bifurcated to form a yoke member 26 adapted to straddle a washer 13 on the stem 13, and if desired a bearing piece or boss 25 for the forward edge of the member may be provided on the adjacent side wall of the casing. Immediately above said yoke 2-8 the member has fixed thereon a guide stud 2T projecting into a cam slot 28 which is formed in the plate or disk portion. T of the bracket 7. Said disk is fixed upon the. stem 13 as by being secured to an annular flange 30 formed on said stem. It will be seen that in the rotation of the bracket the member 25 of the clamping device is arranged to be operated, the cam being so shaped that in the initial movement of the bracket the jaw is moved into clamping position and held in such position 7 until lever 8 is released and the parts restored by the spring 9.

r The thumb lever S which is operable to efi'ect the swinging movement of the bracket '7, and hence of the tying hill 3, is rigidly secured to the stem 13 by means of a screw 31. For this purpose, the end of the stem .is arranged to project through the side wall of the casing section 1 and also the portion of the hand hold 11 which is secured to said walk and is shaped to provide a non-circular end 32 (dotted lines Fig. 1) adapted to be entered into a similarly shaped opening in thelower end of the lever 8. I

The spring 9,which adapted to restore the parts to normal position after an operation by the thumb lever 8, may be in the form of a torsion spring surrounding the stem. 13 and having one end engaging with a stud 33 on the flange- 30 and its other end rigid with the arcuate .rack member 10 t Fig. I

In the. use of the device, the thread ends to be united are placed in operative relation to the tying bill, being guided into this position by the.-r0unded. edge 5 of the guide member 5 and the forward edges of the stationary members of the clamping device, which are suitably shaped for this purpose. thumb lever 8 swings the bracket 7 to elfect, through the medium of the pinion 4.- and rack 10, the rotation of the tying bill 3 and the clamping of the threads by the clamping device 6. In the initial movement of the lever the. movable jaw of the clamping device is operated into clan'iping position while the tying bill is rotated to form the loops of the knot, in a manner well known. In the continued movement of the lever and while the threads remain clamped by the device (3, the threads are clamped by the tying bill and then severed; and in the final movement of the lever the loops are stripped from otf the tying bill while the ends remain clamped thereby so as to tighten the knot before the thread ends are finally withdrawn from the tying bill.

It will be seen that I have produced a knot-tying implement of a very practical character. The construction is extremely simple and the actuating mechanism is advantageously arranged and wholly enclosed within a small casing from which dust and dirt are effectively excluded.
